Pranayama is the science of breath control. The Sanskrit word pranayama consists of two parts: prana and ayama. Ayama means "stretch" or "extend," and describes the action of pranayama. Prana refers to "life force" or "the energy that is infinitely everywhere." So in practicing pranayama, we are extending our life force. Pranayama is made up of three parts: controlled inhalations, controlled exhalations and holding of the breath. There are three parts to proper relaxation - physical, mental and spiritual relaxation. Relaxation yoga pose relaxes the body and mind, and makes one feel refreshed after doing the asanas and the pranayama. This is why it is an essential part of yoga practice.

General guidelines for pranayama:

* Practice first thing in the morning or right before or right at the end of an asana practice.

* Practice once a day only, and like asana practice, not right before or after food.

* Breathe through the nose at all times, if possible.

* Pranayama practices can be done sitting or in various supported asanas.

* If breathing becomes rough or laboured, or if anxiety sets in, stop and breathe naturally.

* Inhales start from the chest, exhales start from the abdomen.
